Objectives: An important contributor to end-stage renal failure globally is diabetic kidney disease. The current study looked at the safeguarding results of an infusion of Ethanol from Lannea coromandelica houtt leaves (ELCL)in diabetic kidney disease that was caused by streptozotocin with the intention to treat diabetic nephropathy, creating supportive and substitute medicine is necessary. The development of DN may be slowed down by itsanti-inflammatory, anti-diabetic and antioxidant qualities. The novelity lies in the plant selection for the study. Methods: Streptozotocin (45mg/kg, i.p.) was administered as a single dosage to rats to induce diabetes. During 8 weeks, oral dosages of ELCL (100mg/kg and 200mg/kg.) were given to rodents with STZ diabetes. Blood sugar amounts and body and kidney weights were measured at the conclusion of the trial period. The parameters of serum and urine were evaluated. The kidney levels of lipid peroxide and antioxidant enzymes were assessed. Results: In STZ-diabetic rats and rats treated with extract, ethylacetate extract dramatically raised body weight and decreased blood glucose, blood urea levels, blood nitrogen levels, and the creatinine levels. All kidney antioxidants, including glutathione synthetase, glutathione-S-transferase, catalase, superoxide dismutase and NAD(P) H dehydrogenase [quinone]1 were highly upregulated by the extract. Conclusion: According to research, ELCL may have antioxidant, antihyperglycemic, and anti-glycation properties that could slow the progression of diabetic nephropathy.
